Sign Android apk without Eclipse

The Android system requires that all installed applications be digitally signed with a certificate whose private key is held by the application’s developer before submitting it to google play.
The Android system uses the certificate as a means of identifying the author of an application and establishing trust relationships between applications. The certificate is not used to control which applications the user can install. The certificate does not need to be signed by a certificate authority: it is perfectly allowable, and typical, for Android applications to use self-signed certificates.
